WASHING-MACHINE DOLLY.

Application filed November 2, 1928.

This invention relates to improvements in (lollies for washing machines, and particularly to a type in which a plurality of beater stubs or pegs extend from one side of a disk,

and the dolly oscillated within the tub or I washing machine.

An object of the invention is to provide an all-metallic washing machine dolly with a plurality of beater stubs and a central hub extending from one face side of a concaved disk and integral therewith, the stubs preferably hollow and of oblong cross section for increased beater area, and the hub providing a socket for slidingly engaging and connecting over an end of a stem or rock shaft.

Another object of the invention is to provide an all-metal dolly, preferably cast of aluminum alloy to be light in weight, combining the beater stubs and a central hub for attaching a stem or rock shaft into a unitary or integral product of increased durability over the prevailing wooden type of dolly.

Another objectof the invention is to proplurality of beater stubs or pegs connecting to and projecting from one side of the disk,

with the disks of concaved form for freely shedding the water as it is elevated from the washing machine tub, and facilitate in raising the dolly from the water of the tub when immersed therein. I

Other features and advantages of the invention relate to details of. construction for slidably connecting or attaching a-stem or rock shaft to and within a central hub of the dolly, and to other structural details more fully set forth and explained in the description of the accompanying drawings forming a part of this specification, in which:

Figure 1 is a top plan View of the improved dolly. a I Figure 2 is a sectional view taken on line 2-2, Figure 1, showing the interior construction of thedolly and the mounting of the lower end of the center shaft therein.

Figure 3 is a sectional view taken on line 33, Figure 2, further detailing the mount ing of the center shaft.

Referring to the drawings, 1 represents a thin metal disk'of concaved form having an vide a washing machine dollyemploying a Serial No. 316,800.

annular rim or flange 2 extending from the upper side thereof. The disk centrally from its lower side is provided with a tubular hub 3 for the reception of an end of a stem or rock shaft at.

A longitudinally slotted sleeve 5 is engaged within the bore of the hub and rigidly secured thereto by means of screws 6, the slots 7 open to the bore of the sleeve providing keyways for a pair of pins 8-8 engaged through the shaft, relatively at right angles, furnishing means for splining the shaft to the sleeve or hub, rotat'rvely connecting the dolly to the end of the shaft. The up er end of the sleeve is closed by a collar 9 xed to the disk or hub portion thereof by means of screws 10.

A plurality of beater stubs-l1, preferably four in number, in a right angled relation, extend from the lower face side of the disk and cast integral therewith. Each stub is of hollow or cored formation, oblong in cross section, along an axis diametric to the axis of the dolly to present opposite broadsides increasing the area of beater, with the lower end of the stub closed. The stubs inwardly at their upper ends curve toward the disk to the hub.

A skeleton or ring form of cover plate 12 is engaged within the rim of the disk, having inward extensions 13 for covering the upper core openings of the stubs so as to seal the same.

The dolly is of simple design to enable the parts to be cast integral and form a rigid durable structure, and preferably cast of an aluminum alloy, reducing its weight over the prevailing all-wood dollies. The disk portion is concaved or curved to drain or shed the water as it is withdrawn from the tub, facilitating in withdrawing the dolly, and being light in weight is not as harsh upon the rock shaft under centrifugal action when changing or reversing the direction of oscillation.

The dolly is rocked or oscillated within the washing machine tub for agitating the clothes, and when light in weight reduces the backlash upon the shaft and transmissioning mechanism therefor when. reversing its direction of oscillation, reducing the wearon the transmission mechanism and reversing sleeve concentrically engaged and secured jar to the relief of the motor of a power driven within the bore of the hub, and a shaft en- 10 Washing machine. gaged into said sleeve having a splined con- Having described my invention, I claim: nection therewith.
